According to BuzzFeed, chaiOS was originally discovered by software developer Abraham Masri, who posted his findings to Github. Masri said his intentions were good — he had alerted Apple to the bug ahead of time and said he only posted it publicly to get Apple's attention.

Masri's original post has since been taken down, but the link may still be floating around, according to BuzzFeed.

Because of the way links work in iMessage — the app generates previews of links before you click on them — you can be affected by chaiOS without even clicking on the link itself. The link preview contains the bug, and it can freeze iMessage all on its own. The bug is capable of crashing iMessage altogether, and in some cases, forcing you to restore your phone to factory settings.

The bug affects phones running iOS 10 up to at least iOS 11.2.5 beta 5, according to BuzzFeed.
